A new study finds that obesity might affect your brain. 

In a new research paper published in the Journal of Neuroscience, researchers say that lab testing in mice suggests diminished brainpower in dramatically overweight animals.

The obese mice, which weighed nearly 40 percent more than the control group, showed diminished reasoning and memory skills when confronted with puzzles also given to the control animals. The overweight mice had problems remembering how to navigate mazes that were easily navigated by the thinner mice. The possible reason? Microglia.

Researchers looking at the mice brains found that the obese mice had a greater number of microglia, which are a type of “scavenger” cell that serve the immune system in the central nervous system.These cells aren’t “bad,” per se, but an increase in their numbers is thought to cause damage to the tiny stalks on nerve cells that receive messages that are vital for the brain to process information.
